摘　　要：[目的]对区域综合治理现状进行评估,为政府制定政策提供相关理论依据。[方法]将DPSIR概念模型引入流域综合治理生态环境效应评价指标体系,并运用AHP-熵权法和TOPSIS法对黄河内蒙古段十大孔兑综合治理现状进行生态环境效应评估。[结果]十大孔兑综合治理现状评价值由高到低为:罕台川>西柳沟>哈什拉川>呼斯太河>毛不拉>木哈尔河>东柳沟>卜尔嘎色太沟>黑濑沟>壕庆河。综合效应指数呈中间高,两边低的趋势,仅罕台川等级为Ⅱ级,其他孔兑都为Ⅳ级,各孔兑整体上生态环境效应指数较低,综合治理现状较差。[结论]DPSIR-TOPSIS模型内部结构清晰,较好地解释了流域综合治理工程与环境—经济—社会系统间的内在联系,评价方法采取了主客观相结合的方法,也更为合理,为流域综合治理生态环境效应提供了一种新的方法和思路。[Objective]To assess the benefits of comprehensive management and provide support for government policy making.[Methods]The concept of DPSIR model was introduced into the eco-environment benefit evaluation index system.AHP-entropy and TOPSIS method was used to evaluate the eco-environment benefit of the comprehensive management in ten tributaries in Inner Mongolia section of the Yellow River.[Results]Value of the integrated management in ten tributaries from highest to lowest was：HantaichuangXiliugou Hashilachuang Husitaihe〉Maobula〉Muhaerhe〉Dongliugou 〉Boergasetaigou 〉Heilaigou〉Haoqinghe.The comprehensive effect index was high in the middle,but low in both sides.Hantaichuan was classⅡ,while the other tributaries was classⅣ,and the comprehensive management in this region was poor.[Conclusion]The internal structure of the DPSIR-TOPSIS model was clear,and it well explained the intrinsic link between watershed comprehensive management engineering and environment-economy-society system.This study provides a new method for assessing the eco-environment benefit of comprehensive management.
